Abstract: A manufacturing method of a street lamp pipe for preventing adhesion of stickers and protecting from electric shock, a street lamp pipe manufactured thereby and a manufacturing device of a street lamp pipe are provided to prevent advertisement paper such as stickers from being attached on the outer surface of a street lamp pipe by sandpapering the outer surface of a street lamp pipe automatically for making the surface rough, and attaching an insulating layer and attaching stone powder for preventing the separation of stone powder, and to prevent an accident of pedestrians by preventing an accident by electric shock with an insulating layer. A manufacturing device(A) of a street lamp pipe for preventing adhesion of stickers and protecting from electric shock comprises a support frame(1) having the sufficient length and height for manufacturing a street lamp pipe(B), a drawer type impurity housing box(2) installed to the lower part of the support frame to be detachable, a bottom closed type partition(3) installed to the upper part of the impurity housing box, a street lamp pipe manufacturing part(4) installed to the upper part of the bottom closed type partition and rotated by making the upper part engage with the lower part of the street lamp pipe, a top closed type partition(5) installed to the upper part of the street lamp pipe manufacturing part, and an infrared lamp drying part installed to the upper part of the top closed type partition. A manufacturing method of a street lamp pipe for preventing adhesion of stickers and protecting from electric shock comprises the steps of: fixing a street lamp pipe to a street lamp manufacturing part; rotating the fixed street lamp pipe, sandpapering down the surface and washing with water; drying the wet street lamp pipe with an infrared lamp drying part; spraying thinner paints for impurity removal to the surface of the street lamp pipe; drying the paints attached to the outer surface of the street lamp pipe with an infrared lamp drying part; spraying stone powder binder to the outer surface of the street lamp pipe; drying the stone powder binder with the infrared lamp drying part; mixing stone powder with the stone powder binder and spraying; drying the attached stone powder with the infrared lamp drying part; spraying transparent enamel paints for discoloration prevention of stone powder on the surface of the street lamp pipe; and drying the sprayed transparent enamel paints with the infrared lamp drying part. The manufactured street lamp pipe includes a rough sanding part formed on the outside of a street lamp pipe main body, a thinner paint layer for impurity removal formed on the sanding part, a stone powder auxiliary binder layer formed on the thinner paint layer for impurity removal, a stone powder binder layer formed on the stone powder auxiliary binder layer, and a transparent enamel paint layer for discoloration prevention of stone powder, wherein the surface of the street lamp pipe is rugged to prevent the adhesion of stickers, and the thinner paint layer and the stone powder binder layers are made of insulating materials to prevent an accident from electric shock caused by a leakage of electricity.
